Flexible framework for fluid topology optimization with OpenFOAM® and finite element-based high-level discrete adjoint method (FEniCS/dolfin-adjoint)

In order to implement the topology optimization method, it is necessary to simulate the fluid flow dynamics and also obtain the sensitivities with respect to the design variable (such as through the adjoint method). However, more complex fluid flows, such as turbulent, non-Newtonian, and compressible flows, may turn the implementation of these two aspects difficult and non-intuitive. In order to solve this deadlock, this work proposes the...
